High energy physics


MPPC is detectors capable of detecting very weak scintillation light. Because of their advantages of being compact, highly stable, and unaffected by magnetic fields, these detectors are likely useful not only in calorimeter detectors in high energy physics experiments but also in new fields.

Case study

T2K experiment

The High Energy Accelerator Research Organization (KEK) and the Japan Atomic Energy Agency (JAEA) are conducting a joint experiment at the Japan Proton Accelerator Research Complex (called J-PARC) being built in Tokai-mura (Ibaraki Prefecture). This experiment called “T2K” (Tokai to Kamioka) will verify whether or not the neutrino has mass, by sending neutrino beams to Super-Kamiokande (Gifu Prefecture, about 300 km away from Tokai-mura). A large number of MPPCs (62,000 pieces) are used in monitoring the neutrino beams in this experiment.
